AIX 5.3 best practices for oracle DB 10.2.0.4

customer is using AIX 5.3 (AIX PROD_aix 3 5 000CA2A2D900) and DB version is 10.2.0.4
DB is critical & Recently getting migrated to AIX from WIndows.
To make sure we don't face any probs after migration,we are implementing best practices at OS level .. so far we've implemented following.
1)All dbf's are existing on JFS2 filesystem -- We've enabled CIO for mount points(dbf's,redo's)
2)Changed the AIX_THREAD_SCOPE to S , previously AIX_thread_scope was set to P
3)Changed minperm% to 5% and maxperm% to 20%
Do we need to change the memory page size to best fit DB needs? or do we need to use large pages?,Any Document available from IBM? what is default pagesize used(how to check)?
How to check NIC is 100mbps or 1gbps?what is the command.
thanks in advance..

IBM whitepaper "Oracle Architechture and Tuning on AIX" might be a good starting point. Not just a list of "magic" settings, but some real content as well.
Some comments about the settings you've implemented so far:
1) Be sure to use an allocation unit size of 512B for filesystems storing redo logs and control files, it's required for direct i/o to work correctly.
3) Since you're using CIO, it might be a good idea to set VMM to steal only file pages (lru_file_repage).
As for the large pages, you have quite a few options. Smaller large pages can be handled more dynamically, whereas bigger ones can provide more performance gains, but can also cause problems if you over-allocate. But, if you didn't need to use large pages on Windows, chances are that you might not necessarily need them on AIX either.
And as always, be careful with "best practices" and "rules of thumb"; it's far better to test different configurations thoroughly than to blindly rely on generic recommendations based on Codd knows what.

Universe Design Best Practices for Oracle

Hello All,
We recently moved from XIR2 on MS SQL 2005 to XI 3.1 on Oracle. This has been a difficult move for us as my team is new to oracle. I'm currently working on several performance issues between BOBJ and Oracle and am looking for documentation on best practices for universe design with oracle. I've foudn tidbits here and there regrading using parameters joing_by_sql and boundary_weight_table, wondering if there are other options out there that might help. We have queries taking 45+ minutes to run and that is totally unacceptable.
thanks
Andrea

I am not sure if you are looking for Optimization or anything else. sorry for that following link might help you considering Oracle as DB.

Best practice for oracle 10.2 RAC with ASM

Did any one tried/installed Oracle 10.2 RAC with ASM and CRS ?
What is the best practice?
1. separate home for CRS, ASM and Oracle Database?
2. separate home for CRS and same home for ASM and Oracle Darabase?
we set up the test environment with separate CRS, ASM and Oracle database homes, but we have tons of issues with the listener, spfile and tnsnames.ora files. So, seeking advise from the gurus who implimeted/tested the same ?

I am getting ready to install the 10gR2 database software (10gR2 Clusterware was just installed ) and I want to have a home for ASM and another for database as you suggest. I have been told that 10gR2 was to have a smaller set of binaries that can be used for the ASM home ... but I am not sure how I go about installing it. The first look at the installer does not seem to make it obvious...Is it a custom build option?

Symantec antivirus Best practice for oracle database on windows server 2003

Hi all,
I have an oracle database server on windows server 2003 platform of version 10.2.0.4. what would be best practice of running symantec antivirus on that server as well as database file exclusions from scanning them.
My server had rebooted unexpectedly for many times. in event log i have id as 6008. what may be cause of it..?

Normally, you don't run a virus scanner on a database server because your database server isn't vulnerable to viruses. It's behind firewalls, people aren't reading mail on it, people aren't plugging thumb drives into it, etc. If you do decide that you need to run a virus scanner on a database server, at least exclude the Oracle data files from the scan. Oracle gets very unhappy if someone else tries to open its data files (or, worse, if someone opens a data file before it gets the chance to acquire exclusive access).

SAP Best practice for Oracle installation on HPux

Hi - I am looking for SAP best practices document to install ERP6 on Oracle 10G platform HPUNIX 31. Is there any sap best practices guide?
Also, for Dev system, I am planning to install ABAP and JAVA stacks in one database. What do I need to do in database level?
Last, How am I going to configure the 2 engines to communicate?
Any reference to documents will be appreciated.
Regards
k

Hi,
Sorry but I'm going to be a bit bold here.
All needed information is on the guides.
1) If you are on Windows, you put the SAP-Oracle CD/DVD in, execute the command mentioned on the installation guide type the two things mentioned on the guide and press next next next. Then you install SAP
2) if you are on UNIX, you start SAP installation, then it stops and tell you to install Oracle. The guide tells you to run RUNINSTALLER (in capitals) you type the two things mentioned on the guide and press next next next. Then you continue the SAP installation.
Of course, those are the simplified versions
No response file is generated "ever". The response file comes INSIDE the installation CDs, for that reason is very important to execute the EXACT commands mentioned on the installation guides, in order to use such, already existing, response file.
I do not understand this need of super-hiper detailed step by step guides.
If you get one like that, then it will be obsolete after one month because there are new Oracle parameters, new oracle patches/patch sets or new .... that have to be done

Best Practice for starting & stopping HA msg nodes?

Just setup a cluster and was trying to start-msg ha and getting error about watcher not being started. Does that have to be started separately? I figured start-msg ha would do both.
For now I setup this in the startup script. Will the SMF messaging.xml work with HA? Whats the right way to do this?

Best practice for integrating oracle atg with external web service

Hi All
What is the best practice for integrating oracle atg with external web service? Is it using integration repository or calling the web service directly from the java class using a WS client?
With Thanks & Regards
Abhishek

Using Integration Repository might cause performance overhead based on the operation you are doing, I have never used Integration Repository for 3rd Party integration therefore I am not able to make any comment on this.
Calling directly as a Java Client is an easy approach and you can use ATG component framework to support that by making the endpoint, security credentials etc as configurable properties.

Best Practice for Extracting a Single Value from Oracle Table

I'm using Oracle Database 11g Release 11.2.0.3.0.
I'd like to know the best practice for doing something like this in a PL/SQL block:
DECLARE
    v_student_id    student.student_id%TYPE;
BEGIN
    SELECT student_id
    INTO    v_student_id
    FROM    student
    WHERE   last_name = 'Smith'
    AND     ROWNUM = 1;
END;
Of course, the problem here is that when there is no hit, the NO_DATA_FOUND exception is raised, which halts execution. So what if I want to continue in spite of the exception?
Yes, I could create a nested block with EXCEPTION section, etc., but that seems clunky for what seems to be a very simple task.
I've also seen this handled like this:
DECLARE
    v_student_id    student.student_id%TYPE;
    CURSOR c_student_id IS
        SELECT student_id
        FROM    student
        WHERE   last_name = 'Smith'
        AND     ROWNUM = 1;
BEGIN
    OPEN c_student_id;
    FETCH c_student_id INTO v_student_id;
    IF c_student_id%NOTFOUND THEN
        DBMS_OUTPUT.PUT_LINE('not found');
    ELSE
        (do stuff)
    END IF;
    CLOSE c_student_id;
END;
But this still seems like killing an ant with a sledge hammer.
What's the best way?
Thanks for any help you can give.
Wayne

Do not design in order to avoid exceptions. Do not code in order to avoid exceptions.
Exceptions are good. Damn good. As it allows you to catch an unexpected process branch, where execution did not go as planned and coded.
Trying to avoid exceptions is just plain bloody stupid.
As for you specific problem. When the SQL fails to find a row and a value to return, what then? This is unexpected - if you did not want a value, you would not have coded the SQL to find a value. So the SQL not finding a value is an exception to what you intend with your code. And you need to decide what to do with that exception.
How to implement it. The #1 rule in software engineering - modularisation.
E.g.
create or replace function FindSomething( name varchar2 ) return foo.col1%type is
id foo.col1%type;
begin
select col1 into id from foo where col2 = upper(name);
return( id );
exception when NOT_FOUND then
return( null );
end;
And that is your problem. Modularisation. You are not considering it.
And not the only problem mind you. Seems like your keyboard has a stuck capslock key. Writing code in all uppercase is just as bloody silly as trying to avoid exceptions.

Best practice for install oracle 11g r2 on Windows Server 2008 r2

Dear all,
May I know what is the best practice for install oracle 11g r2 on windows server 2008 r2. Should I create a special account for windows for the oracle database installation? What permission should I grant to the folders where Oracle installed and the database related files located (datafiles, controlfiles, etc.)
Just grant Full for Administrators and System and remove permissions for all others accounts?
Also how should I configure windows firewall to allow client connect to the database.
Thanks for your help.

Best Practices for BI, ADF and Oracle Forms installations on Weblogic

Hi, I'm researching options on upgrading to Oracle 11g Middleware. My company currently has Oracle Forms 10g running on Oracle Application Server.
We are interested in using Oracle Forms 11g, ADF and Jdeveloper, and Business Intelligence with Oracle's Weblogic 10.3.5.
Is there any whitepapers or documentation on best practices for installing alll of these components together?
For instance, can ADF ( with JSF 2.x ) be installed in the same domain as Oracle Forms 11g but use different managed servers?
Will Business Intelligence need to be in a seperate Oracle Home with it's own weblogic installation? I spend a lot of time trying to get the JSF upgraded to 2.x in the Business Intelligence installation and could not get it to work.
I know it's a pretty broad question but thank you for any direction on this.

Thanx for the reply! I read through the documents and they are very good at explaining how to install the different components individually. I still can't find much on installing them together. I hope it's not just going to be a trial and error thing.
So far I've installed done the following successfully:
Installed 10.3.5 weblogic
Forms and Reports 11g on top of 10.3.5
I've created an additional managed server for our ADF applications.
My next step is upgrading the JSF to 2.x. I would have to stage patches 12917525 and 12979653. I'm afraid it will break the forms and reports though. Any ideas?

Best Practices for user ORACLE

Hello,
I have few linux servers with user ORACLE.
All the DBAs in the team connecting and working on the servers as ORACLE user and they dont have sperate account.
I create for each DBA its own account and would like them to use it.
The problem is that i dont want to lock the ORACLE account since i need it for installation/upgrade and etc , but yet i dont what
the DBA Team to connect and work with the ORACLE user.
What are the Best Practice for souch case ?
Thanks

To install databases you don't need acces to Oracle.
Also installing 'few databases every month' is fundamentally wrong as your server will run out of resources, and Oracle can host multiple schemas in one database.
"One reason for example is that we have many shell scripts that user ORACLE is the owner of them and only user ORACLE have a privilege to execute them."
Database control in 10g and higher makes 'scripts' obsolete. Also as long as you don't provide w access to the dba group there is nothing wrong in providing x access.
You now have a hybrid situation: they are allowed interactively to screw 'your' databases, yet they aren't allowed to run 'your' script.
Your security 'model' is in urgent need of revision!

Best Practice for Securing Web Services in the BPEL Workflow

What is the best practice for securing web services which are part of a larger service (a business process) and are defined through BPEL?
They are all deployed on the same oracle application server.
Defining agent for each?
Gateway for all?
BPEL security extension?
The top level service that is defined as business process is secure itself through OWSM and username and passwords, but what is the best practice for security establishment for each low level services?
Regards
Farbod

It doesnt matter whether the service is invoked as part of your larger process or not, if it is performing any business critical operation then it should be secured.
The idea of SOA / designing services is to have the services available so that it can be orchestrated as part of any other business process.
Today you may have secured your parent services and tomorrow you could come up with a new service which may use one of the existing lower level services.
If all the services are in one Application server you can make the configuration/development environment lot easier by securing them using the Gateway.
Typical probelm with any gateway architecture is that the service is available without any security enforcement when accessed directly.
You can enforce rules at your network layer to allow access to the App server only from Gateway.
When you have the liberty to use OWSM or any other WS-Security products, i would stay away from any extensions. Two things to consider
The next BPEL developer in your project may not be aware of Security extensions
Centralizing Security enforcement will make your development and security operations as loosely coupled and addresses scalability.
Thanks

BEST PRACTICES FOR CREATING DISCOVERER DATABASE CONNECTION -PUBLIC VS. PRIV

I have enabled SSO for Discoverer. So when you browse to http://host:port/discoverer/viewer you get prompted for your SSO
username/password. I have enabled users to create their own private
connections. I log in as portal and created a private connection. I then from
Oracle Portal create a portlet and add a discoverer worksheet using the private
connection that I created as the portal user. This works fine...users access
the portal they can see the worksheet. When they click the analyze link, the
users are prompted to enter a password for the private connection. The
following message is displayed:
The item you are requesting requires you to enter a password. This could occur because this is a private connection or
because the public connection password was invalid. Please enter the correct
password now to continue.
I originally created a public connection...and then follow the same steps from Oracle portal to create the portlet and display the
worksheet. Worksheet is displayed properly from Portal, when users click the
analyze link they are taken to Discoverer Viewer without having to enter a
password. The problem with this is that when a user browses to
http://host:port/discoverer/viewer they enter their SSO information and then
any user with an SSO account can see the public connection...very insecure!
When private connections are used, no connection information is displayed to
SSO users when logging into Discoverer Viewer.
For the very first step, when editing the Worksheet portlet from Portal, I enter the following for Database
Connections:
Publisher: I choose either the private or public connection that I created
Users Logged In: Display same data to all users using connection (Publisher's Connection)
Users Not Logged In: Do no display data
My question is what are the best practices for creating Discoverer Database
Connections.
Is there a way to create a public connection, but not display it in at http://host:port/discoverer/viewer?
Can I restrict access to http://host:port/discoverer/viewer to specific SSO users?
So overall, I want roughly 40 users to have access to my Portal Page Group. I then want to
display portlets with Discoverer worksheets. Certain worksheets I want to have
the ability to display the analyze link. When the SSO user clicks on this they
will be taken to Discoverer Viewer and prompted for no logon information. All
SSO users will see the same data...there is no need to restrict access based on
SSO username...1 database user will be set up in either the public or private
connection.

You can make it happen by creating a private connection for 40 users by capi script and when creating portlet select 2nd option in Users Logged in section. In this the portlet uses there own private connection every time user logs in.
So that it won't ask for password.
Another thing is there is an option of entering password or not in ASC in discoverer section, if your version 10.1.2.2. Let me know if you need more information
